摘要：
Al(111) oxidation has been subjected to numerous studies using surface analysis techniques. Indeed it seems to have been used as a proving ground for techniques to establish the detail each can shed on the determination of the adsorption site of O on a clean Al(111) surface. In this first detailed ion scattering study of the oxidation of the Al(111) surface it has been established that at exposures of up to 100 L almost one monolayer of oxygen is adsorbed to the surface. This observation alone brings into question many models which conclude that the adsorption leads to a surface, and subsurface layer of oxygen. Furthermore, by using shadowing and blocking associated with medium energy ion scattering (MEIS) it has been possible to exclude the existence of a significant subsurface site at exposures up to 100 L.
